Step-by-Step Solution

Answer

The difference is \( \$251 \)

Step 1: Identify the given values

Determine the regular price and the sale price from the problem. The regular price is \( \$650 \) and the sale price is \( \$399 \)

Step 2: Subtract the sale price from the regular price

Step 3: Perform the subtraction

Calculate \[ 650 - 399 = 251 \]

Key Concepts

Price Difference

When shopping, understanding price differences can save you money. This exercise asks us to find how much cheaper a mountain bike is when it's on sale. The regular price is \(650, and the sale price is \)399.
To find the price difference, you subtract the sale price from the regular price. This helps you see how much money you'd save by buying the bike on sale.
Knowing how to calculate price differences is useful when budgeting or comparing products. It's a basic skill that helps you make informed financial decisions.

Step-by-Step Solution

A step-by-step approach breaks down the problem into manageable parts. Let's look at the steps for our exercise:

• Step 1: Identify the given values - The regular price is \(650, and the sale price is \)399.
• Step 2: Subtract the sale price from the regular price - Write it down as: \ 650 - 399.
• Step 3: Perform the subtraction - Do the calculation to find the difference: \ 650 - 399 = 251.

These steps make it easier to tackle subtraction problems. By following them, you’re less likely to make mistakes and more likely to understand the solution thoroughly.

Basic Arithmetic

Basic arithmetic is essential in everyday life. It includes addition, subtraction, multiplication, and division.
In our exercise, we focused on subtraction. This is one of the key operations in arithmetic. Knowing how to subtract correctly helps in various situations, from shopping to budgeting.
Here, we subtracted \(399 from \)650. To do this:

• Start from the rightmost digit and work left.
• If the top digit is smaller than the bottom digit, borrow from the next column.

Practicing basic arithmetic strengthens your problem-solving skills and boosts your confidence in handling numerical tasks.
